6 Claims. (Cl. 22160) This invention relates to multicameral collapsible containers, particularly such as are'designed to hold a diilerent substance in each of the several chambers, the substances being keptapart 5 until the time of use, whenthey are brought into mutual contact for interaction and/or concomitant dispensing.

It is the object of this invention to provide a simple and economical construction for these conl tainers.

Multicameral collapsible containers constructed in accordance with this invention comprise an outer collapsible tube and at least one inner collapsible tube therewithin, each tube having a separate closure at its discharge end. Preferably, the discharge end of the inner tube is openable from without the outer tube; for example, (a) it may be made pressure-responsive by merely pressing its edges together (to give, among other possi- 20 bilities, a diametric rib or a plurality of radial fins), by closing it with a single fold, by forming it with a weakened structure, and/or by applying to it an inert sealing means, such as paramn, or otherwise, or (b) if it presents a relatively broad 25 imper'forate surface;it will be puncturable by a prod introduced through the opened dischargeend oi the outer tube or-by a prod fixed to the interior of the outer tube or to the underside of its cap.. The filling ends of all the tubes-the fill- 30 ing end herein means the end opposite the discharge end--may have a joint closure. (for example, being folded together), or may be closed individually.

In one method of assembling the multicameral collapsible container, the outer tube, which may be the conventional soft-metal collapsible tube, its discharge end being closed, is partially filled in the customary manner (space being reserved for the inner tube), thefilling end being left open; 40 (a) the inner tube, which may be a cylindrical tube of the same material as the outer tube but of smaller diameter, its discharge end being closed, is filled, and, its filling end being left open,'is inserted, discharge end foremost, into the outer and practice of the invention will be facilitated by reference to the accompanying drawings,

wherein:

Figures 1 and 2 are, respectively, a longitudin view and a side elevation The understanding of the objects, advantages,

nal top view and a side elevation or one form 01' a the inner tube:

Figure 3 is a longitudinalside view oi another form or the inner tube;

Figures 4 and 5 are, respectively, alongitudinal topview and a longitudinal side view of still another form oi. the inner tube;

Figures 6 and 7 are, respectively, a perspective the inner tube;

Figures 8 and 9 are, respectively, a dischargeend view and a perspective view of again another form of the inner tube:

Figures 10 and 11 are, respectively, a dischargeend view anda perspective view of a modification 90! the inner tube represented by Figures 8 and I Figures 12, i3, and 14 are, respectively, a discharge-end view, a longitudinal top view, and a longitudinal side view of amodification of the inner tube represented by Figures 4 and 5;

oi yet anotheriorm or Figures 15 and 16are, respectively, a longitudinal top view and a longitudinal side view, partly in section, 01' a complete multicameral collapsible container, havingan inner tube of the type represented by Figures 4 and 5; and

Figure 17 is a medial transverse sectional view of a complete multicameral collapsible bontainer having two inner tubes.

In the drawings, I 5 is an inner tubewhose discharge end is closed by pressing its edges together to give a diametric rib I6; "is an inner tube having its discharge endclosed by a single fold I8 (the corners of which may, additionally, be turned down); 19 is an inner tube having its discharge end closed by a single told 20, the cylindricity of the tube, and therefore, its capacity, being maximized by rounding the portion adjacent to the told, as at 2i (e. g. with the aid of a suitable internal former); 22 is, an inner tube whose dis charge end is closed by an integral relatively broad imperforate head 23, which may have a transver se groove 24, to serve as a passage for the contents oi the outer tube in the; event they are otherwise obstructed, and a small central depression 25, at which the material or the inner tube may be thinned, to facilitate puncture by a prod introduced from with8ut; 26 is an inner tube whose discharge end is closed by pressing its edges together to give four radial fins 21 (the corners of which may, additionally, be folded over, as at 28) which; in virtue of not extending latrally beyond the walls of the tube, do not impose an upper tube whose discharge end is closed by a told 30 limit on its relative diameter; and 29 is an inner that, being crimped (i. e. corrugated, as by means of appropriate dies), likewise does not extend beyond the walls or the tube. Outer tube 3| may be a conventional collapsible tube, with shoulder, neck, and cap (or, optionally, applicator nozzle), at its discharge end; within it is the inner tube; and the filling ends of the two may be interfolded and a clip superimposed, or they may be separately folded and clipped, as at 32 and 33; or there may be two (or more) inner tubes 34, which may be of predominantly oval transverse section and may be closed independently of each other and of the outer tube 35. v

To use such multicameral collapsible containers as have been described above, the closure at the discharge end of the outer tube is removed; the

discharge end of the inner tube is opened (a) by pressing on theouter tube, which pressure is com-' municated to the inner tube and opens the pressed-together edges and/or the folds at its dis-' charge end or breaks the discharge end at its weakened places,- or (b) by introducing a prod through the orifice of the outer tube and puncturing the discharge end of the inner tube therewith;

and the contents of the two tubes are-brought into mutual contact and concomitantly dispensed by continued pressure on the outer tube.

It is to be understood that the foregoing examples are merely illustrative and by no means limi tative of the invention, which may be variously otherwise embodied withinthe scope of the appended claims.

We claim:

1. A multicameral collapsible container comprising an outer collapsible tube and at least one inner collapsible tube therewithin, the discharge end of theputer tube having a closure, and the discharge end or each inner tube being closed by a fold, the discharge end of each inner tube being openable by pressure exerted from without the outer tube. I I

2. A multicameral collapsible container comprising an outer collapsible tube'and at least one inner collapsible tube therewithin, the discharge end of the outer tube having a closure, and the discharge end of each inner tube being closed by a crimped told, the discharge end 01' each inner tube being openable by pressure exerted from without the outer tube. V

-3. A multicameral collapsible container comprising an outer collapsible tube and at least one inner collapsible tube therewithin, the discharge end of the outer tube having a closure, and the discharge end of each inner tube being closed by pressing its edges together, the discharge end of each inner tube being openable by pressure exerted from without the outer tube.

4. A multicameral collapsible container comprising an outer collapsible tube and at least one inner collapsible tube ther'ewithin, the discharge end of the outer' tube having a closure, and the discharge end of each inner tube being closed by pressing its edges together to give a plurality of radial fins, the discharge end of each innerv tube being openable by pressure exerted from without the outer tube. v

5. A multicameral collapsible container comprising an outer collapsible tube and at least one inner collapsible tube, each tube having a separate and independent closure at its discharge end, and each inner tube and its closure being entirely within the outer tube, each tube containing a separate substance to be dispensed, the discharge I end of each inner tubebeing openablefrom without the outer tube, and the tubes being so constructed and arranged that the contents of all of them are discharged through the opened discharge end of the outer tube.

6. A multicameral collapsible container comprising an outer collapsible tube and at least one inner collapsible tube, the discharge end of the outer tube having a closure and the discharge end of each inner tube being closed by an integral imperforate head, each tube containing a separate substance to be dispensed, and the tubes being so constructed and arranged that the head of each inner tube is puncturabie by a prod introduced throughthe orifice of the opened discharge end of the outer tube and that the contents of all the tubes are tube entirely within the outer.

discharged through the opened discharge end of the outer tube.
